Does anyone know of video footage or court transcripts wherein election fraud is specifically alleged in front of a judge?

He is harping on some talking point he heard in the MSM that Trump's lawyers all said there was no fraud in the courts. And he just stated that if I could come up with one documented case of fraud being alleged in front of a judge he would "keep an open mind on the fraud".

I have been researching myself and it seems all the court cases that specifically alleged fraud were thrown out before they even got before a judge. But if anyone was aware of something I missed, or even just a good response to this particular point that my friend is so stuck on, that would be appreciated.
